Building Information Modelling (BIM) is a dynamic process of creating information-rich models for the entire lifecycle of a construction project. As a project passes through different phases, the level of development in a BIM model also increases to different levels namely LOD 100, 200, 300, and beyond.
A BIM model can be utilized for pre-defined specific purposes, commonly known as use cases. According to project stage requirements and project complexity, specific parameters are added to the existing information contained in BIM. These additions of pre-defined used cases can be described as BIM dimensions.
These dimensions enhance the data associated with a model to share a greater level of understanding of a construction project. In the modern era, BIM technology has evolved from basic 3D & 4D dimensions to more sophisticated 5D, 6D & 7D dimensions that are poised to change the future of the AEC industry.
BIM dimensions – 3D, 4D, 5D, 6D & 7D, each have their own purpose and are useful in finding out how much a project would cost, its timeline, when it would be completed, and how sustainable it would be in the future.
